1. CONNECTION e Before making final connections, make temporary connections ae or oe = pat : : pag

then operate the unit to check for any connecting cord problems. Connections of Cords (Supplied) for Wiring

e Speakers connected to this unit must be high power type with over ae Serrraees — : : )

30W maximum input power and have impedance between 4 and 8 ohms. Be aware of the fact that using a speaker other than the one specified can cause the speaker to be damaged. ©

e Aspecial BPTL circuit is used to be sure that you do notconnectthe speaker directly to ground nor join the left and right speaker (—) leads.

e Different speaker leads have are offered for different car models. The ground wire cannot be used for the left or right speakers lead.

Be sure to use the speaker lead only. e Whenconnecting the cords, be sure to fix them firmly with clamps

or tape. Be sure to protect the cords from damage by taping them Gain Control

at places where they will contact barriers. Wh a ad i ee . : ,

® Toensure that all regular car stereos used in combination with this screwdriver. unit operate properly, be sure to wire the main power supply cable (red) correctly to the respectively determined points. Failure to do so or errors in this process will result in total inoperation.

e Besure to properly connect the color coded leads. Failure to do so can cause malfunctions.

e Use a regular power car stereo with a maximum output of 8.5W

¢ Refer to figure 4 while reading the following descrip-

tion.

1. When + Bis supplied to the TO BATTERY terminal, a volt-

age is applied to terminal (9) of IC3, the muting transistor

inside the IC is turned on and muting is activated.

2. When power is turned on to the external set, + B is sup-

plied to pin (1) of the connector. Muting is cancelled 1.2

seconds after the voltage at terminal (8) of IC3 reaches

2.8V or more.

Fig. 4

3. When a muting output is generated in the external set, a

voltage is applied from pin (4) of the connector to terminal

@ of IC3 and muting is activated when this voltage

reaches 2.8V or more. Muting is cancelled 0.5 seconds

after the voltage drops below 2.8V.

4. The muting restoration time is determined by the discharge

time of the capacitor placed between terminals (D and @)

of 1C3.
